Not sure if you are subscribed to the pim@ietf.org or mcast-wifi@ietf.org mailing lists. There was a call for volunteers to progress IGMP/MLD to standards track not that long ago: "[pim] Volunteers needed for work on progressing IGMP/MLD on the standards track" https://mailarchive.ietf.org/arch/msg/pim/F5y_w6jnrtzBpEiC7F_TxBv9PXI I had voiced some concerns regarding the IGMPv2/MLDv1 report suppression and the querier mechanism and their unfavourable implications, as well as some issues (or ambiguities at least) with RFC4541: https://mailarchive.ietf.org/arch/msg/pim/DWWYpnsZsbqHtafwYZ_swhDpbcQ https://mailarchive.ietf.org/arch/msg/pim/omI4-pg-12vO88YuZcRP5TCz4wY It seems that some bigger vendors had gathered for a phone call: https://mailarchive.ietf.org/arch/msg/pim/jPAbf-PHgtgpwe8lgyjOzCHlhc0 But I haven't heard anything back from that meeting on those lists. Just wanted to forward this, in case you guys might maybe be interested to participate there in some way. :-) Cheers, Linus
